To Reproduce
Steps to reproduce the behavior:

1. Create test package from archive test.zip
2. Try running it with ut_teamcity_reporter()

select * from table(ut.RUN('test',ut_teamcity_reporter()));

3. The output will be similar to this one:

##teamcity[testSuiteStarted timestamp='2020-11-18T12:24:34.326+0000' name='test']
##teamcity[testSuiteStarted timestamp='2020-11-18T12:24:34.327+0000' name='Test']
##teamcity[testStarted timestamp='2020-11-18T12:24:34.328+0000' captureStandardOutput='true' name='stat_int_tests.test.test']
"##teamcity[testStdErr timestamp='2020-11-18T12:24:34.330+0000' name='stat_int_tests.test.test' out='Test exception:|nORA-06512: at ""STAT_INT_TESTS.TEST"", line 7|nORA-06512: at line 6|n|n']"
"##teamcity[testFailed timestamp='2020-11-18T12:24:34.330+0000' details='Test exception:|nORA-06512: at ""STAT_INT_TESTS.TEST"", line 7|nORA-06512: at line 6|n|n' message='Error occured' name='stat_int_tests.test.test']"
##teamcity[testFinished timestamp='2020-11-18T12:24:34.331+0000' duration='1' name='stat_int_tests.test.test']
##teamcity[testSuiteFinished timestamp='2020-11-18T12:24:34.331+0000' name='Test']
##teamcity[testSuiteFinished timestamp='2020-11-18T12:24:34.332+0000' name='test']

Expected behavior
We see error message no data found on top of error stack. Instead the first one is ORA-06512: at ""STAT_INT_TESTS.TEST""
When running with default reporter there is no issue.
